The ADC-DAC Pi Zero is a 2 channel 12 bit analogue to digital converter and 2 channel 12 bit digital to analogue converter designed to work with the Raspberry Pi. Designed for the same footprint as the Raspberry Pi Zero the ADC-DAC Pi Zero is also compatible with full size Raspberry Pi models.

Power to the board is provided through the host Raspberry Pi using the GPIO port. Only one ADC-DAC Pi Zero can be used on a Raspberry Pi but the extended pins on the GPIO connector allow you to stack the ADC-DAC Pi Zero along with other expansion boards. Mounting holes on the board can be used to securely fit the board on your Raspberry Pi. As the ADC-DAC Pi Zero uses the same footprint as the Raspberry Pi Zero only two of the mounting holes can be used on the larger Raspberry Pi models.

The A/D and D/A converters communicate with the Raspberry Pi through the SPI interface.

Assembly

The ADC DAC Pi Zero is supplied with the 40 pin GPIO connector unsoldered. We supply the ADC DAC Pi Zero this way because the Raspberry Pi Zero is also supplied without a GPIO header and the ADC DAC Pi Zero could therefore be fitted both above or below the Raspberry Pi Zero.

Before using the ADC DAC Pi Zero you will need to solder the connector onto the PCB.
